Though it would appear that having more than the 3 Titanosaurs, which we'd thought was for PvP balancing purposes, was server safe I have noticed a small detail that we may have overlooked. Any tests run about the Titanosaurs being safe to have more than 3 on a single game were most likely tested at close range, where they were fully rendered. Here's the issue though.

Titanosaurs render like trees.

Up close the game may appear to be fine, but these dinos and their movements render at long distances too. You can see them much further out than any regular spawn, similarly to tree rendering. This, coupled with not just their size but the fact they are moving AIs can be a lot heavier on the server. Although just going beyond 3 we may be fine, if it piles on too high we can be looking at some bigger issues that effects our game experience.
